Answer:
To achieve the goal, he needs to work all 30 hours, with at least 10 hours on gardening, and the rest mowing.
Step-by-step explanation:
M = $20 per hour mowing
G = $25 per hour gardening
Maximum = 30 hours per week.
To make at least $650 per week, if he does only mowing, he makes only $600.
to make the extra $50, he needs to replace (650-600)/(25-20) = 10 hours of mowing with gardening.
To achieve the goal, he needs to work all 30 hours, with at least 10 hours on gardening, and the rest mowing.
Or if he works all on gardening, he only needs to work 26 hours to make $650 a week.
For adding and subtracting fractions always make sure you have common denominators. Multiplication of fractions allows you to multiply fractions across without having common denominators. For mixed fractions, make sure your whole numbers are multiplied by the denominator and then added to the number in the numerator. If you have checked these steps, you should be good to go with your working and solving.
5)7/5+98/15 →LCD=15→7 14/15
6)46/9-17/6 →LCD=18 →2 5/18
7)multiply across → 4/15
8)multiply across (put a 1 under 12 if that helps) 36/4=9
9)23/4×32/3=736/12 → 61 1/3
10)LCD= 8 →1 3/8
11)(put a 1 under 9 if that helps) LCD=3→13 2/3
12)25/6+17/5 →LCD=30 →7 17/30
